Let's divide 60660431 by 820
We want to divide 60660431 by 820.

Going ahead to step 1:
When dividing 6 by 820, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 820

Let's proceed to step 2:
60 divided by 820 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 820

Advancing to step 3:
606 divided by 820 is 0 with a remainder of 606.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 606 and we're left with 606.
Include the next digit (6) from the dividend after 606, then repeat: 6066 / 820

Advancing to step 4:
820 can be fit into 6066 7 times, resulting in a remainder of 326.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 5740 from 6066, we get 326.
Take the next digit (0) from the dividend and append it to 326, then repeat: 3260 / 820

Let's proceed to step 5:
3260 divided by 820 is 3 with a remainder of 800.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we subtract 2460 from 3260, we get 800.
Fetch the next digit (4) from the dividend, attach it to 800 and continue: 8004 / 820

On to step 6:
820 goes into 8004 9 times with a remainder of 624.
Write down 9 as next digit of the result. 
Result so far: 739.0
The remainder is 624 after subtracting 7380 from 8004.
Fetch the next digit (3) from the dividend, attach it to 624 and continue: 6243 / 820

Advancing to step 7:
6243 divided by 820 is 7 with a remainder of 503.
Use 7 as the next digit of our solution. 
Result so far: 7397.0
The remainder is 503 after subtracting 5740 from 6243.
Take the next digit (1) from the dividend and append it to 503, then repeat: 5031 / 820

On to step 8:
820 goes into 5031 6 times with a remainder of 111.
The next digit of our result is 6. 
Result so far: 73976.0
If we subtract 4920 from 5031, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 9:
When dividing 1110 by 820, we get 1 with a remainder of 290.
Use 1 as the next digit of our solution. 
Result so far: 73976.1
Subtract 820 from 1110 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 10:
820 goes into 2900 3 times with a remainder of 440.
The next digit of our result is 3. 
Result so far: 73976.13
Subtracting 2460 from 2900 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 11:
The number 820 fits into 4400 5 times, leaving a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 73976.135
The remainder is 300 after subtracting 4100 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 12:
820 can be fit into 3000 3 times, resulting in a remainder of 540.
Put 3 as the next digit of the answer. 
Result so far: 73976.1353
The remainder is 540 after subtracting 2460 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 13:
The number 820 fits into 5400 6 times, leaving a remainder of 480.
Record the quotient 6 as the next digit in the result. 
Result so far: 73976.13536
If we take 4920 away from 5400, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 14:
When dividing 4800 by 820, we get 5 with a remainder of 700.
The next digit of our result is 5. 
Result so far: 73976.135365
If we subtract 4100 from 4800, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 15:
820 can be fit into 7000 8 times, resulting in a remainder of 440.
The number 8 becomes the next digit in our result. 
Result so far: 73976.1353658
Subtract 6560 from 7000 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 16:
820 goes into 4400 5 times with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 73976.13536585
Deduct 4100 from 4400 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 73976.13536585 and a remainder of 3e-07.
